Another similar Pi-based KVM is TinyPilot: https://mtlynch.io/tinypilot/

The author was able to use the MJPEG output of the USB HDMI capture devices to get low latency video.

I am the original author of the software that helped TinyPilot achieve this (MJPEG uStreamer) and I wrote it specifically for Pi-KVM :)

According to the blog post, TinyPilot also uses µStreamer (from this Pi-KVM project) to achieve its low latency. The initial revision of TInyPilot couldn't get low enough latency using the HDMI over IP extender otherwise.
